Proto:int gen_pool_add_owner(struct gen_pool *pool, unsigned long virt, phys_addr_t phys, size_t size, int nid, void *owner)

Type:int

Parameter:

Type	Parameter	Name
struct gen_pool *	pool
unsigned long	virt
phys_addr_t	phys
size_t	size
int	nid
void *	owner

186

nbits = size >> minimum allocation order

187

nbytes = sizeof(structgen_pool_chunk) + BITS_TO_LONGS(nbits) * sizeof(long)

190

chunk = vzalloc_node(nbytes, nid)

191

If Value for the false possibility is greater at compile time(chunk == NULL) Then Return -ENOMEM

194

physical starting address of memory chunk = phys

195

start address of memory chunk = virt

196

d address of memory chunk (inclusive) = virt + size - 1

197

private data to retrieve at alloc time = owner
